What is HDI PCB
HDI PCB: High density interconnect PCB, are a way of making more room on your printed circuit board to make them more efficient and allow for faster transmission. It’s relatively easy for most enterprising companies that are using printed circuit boards to see how this can benefit them.
Advantages of HDI PCB
The most common reason for using HDI technology is a significant increase in packaging density. The space obtained by finer track structures is available for components. Besides, overall space requirements are reduced will result in smaller board sizes and fewer layers.
Usually FPGA or BGA are available with 1mm or less spacing. HDI technology makes routing and connection easy, especially when routing between pins.
